Transmittance and near-field characterization of sub-wavelength tapered optical fibers
journal contribution
posted on 2023-06-08, 00:20 authored by Fedja OrucevicFedja Orucevic, Valérie Lefèvre-Seguin, Jean HareWe have produced high transmission sub-wavelength tapered optical fibers for the purpose of whispering gallery mode coupling in fused silica microcavities at 780 nm. A detailed analysis of the fiber transmittance evolution during tapering is demonstrated to reflect precisely the mode coupling and cutoff in the fiber. This allows to control the final size, the number of guided modes and their effective index. These results are checked by evanescent wave mapping measurements on the resulting taper.
